Title: Magnetic disk device
Inventor: TERAJIMA AYA
IPC: G11B21/08
Filed: 1993-08-11
Abstract: PURPOSE:To process a large amount of data at a high speed by calculating a position for writing data on a magnetic disk and controlling a magnetic head based on the rotational speed of the magnetic disk and the processing time of a CPU. CONSTITUTION:When writing position calculating means 10 receives a writing request from a host device 50, the means 10 calcutes a writing position based on the processing time of a CPU 30 and the rotational speed of the magnetic disk. The position of a magnetic head 40 is controlled by a head position control means 20 in accordance with the result of this calculation, when the processing time of the CPU is smaller than that for one block rotation of the magnetic disk, data of (n) block are continuously written every one block, when the processing time of the CPU is longer, writings are continuously carried out for every block number corresponding to the processing time and thus, a larger amount of data is processed at a high speed compared with the case where writing is carried out by one block at one rotation of the magnetic disk. Further, when reading is carried out, a head position is controlled by the means 20.

Title: Radar transmitting apparatus
Inventor: TAKIGUCHI NOBORU
IPC: G01S7/282
Filed: 1988-09-01
Abstract: PURPOSE:To decrease radiowaves emitted from an antenna and to make it difficult to detect the radiowave by an enemy radiowave detector by connecting a dual TR tube circuit comprising hybrid circuits, dual TR tubes and small- power dummy loads to a waveguide. CONSTITUTION:A high power transmitted wave which is outputted from a radar transmitter 1 is inputted into a dual TR tube circuit 9 through a waveguide switch 3. TR tubes are discharged in the circuit 9. Therefore the total power is transmitted to a circulator 5 and an antenna 7. When the switch 3 is changed over, the high-power transmitted wave is transmitted to the switch 3 and a dummy load 4 and absorbed in this part. A part of the leaked transmitted wave through the isolation of the switch 3 is inputted into the circuit 9. The TR tubes in the circuit 9 are not discharged. The transmitted wave is transmitted into inner small-power dummy loads 12. In this way, the radiowaves which are radiated from the antenna 7 into a space are decreased, and the radiowaves are not detected by an enemy radiowave detector.

Title: Separation of oil and water
Inventor: GOSHIMA NOBUTAKA
IPC: B01D17/06
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To conveniently, economically and almost completely separate oil and water by applying an electric field on an aq. emulsion wherein plural oil drops are suspended to aggregate the drops and separating the oil layer formed. SOLUTION: A meshy feeder anode terminal 13 and a feeder cathode terminal 14 are respectively provided close to the upper and lower ends of a cylindrical electric cell main body 12. Plural spongy fixed-bed carbonaceous electrodes 15 are laminated between both terminals 13 and 14. A meshy diaphragm and a spacer 16 are placed between the electrodes. A current is applied while supplying an aq. emulsion from the lower part of the cell 12, hence the lower face of the fixed bed is positively polarized and the upper face negatively polarized, and a porous anode is formed on the lower face of the fixed bed 15. Consequently, the aq. emulsion is brought into contact with the porous anode and aggregated, and aggregation is similarly caused at the porous cathode on the upper face. The oil drops are increased in diameter in this way, and the oil layer formed is separated.

Title: Communication controller
Inventor: HOUKAN SACHIKO
Filed: 1987-09-02
Abstract: PURPOSE:To allow a CPU to manage plural logic channels without notifying a channel number by preparing memories by logic channels and using the memories switchingly for each channel. CONSTITUTION:When an I/F control section 11 receives a data packet from a network, a CPU 14 checks to which channel the data is given and informs the channel number corresponding to the data to a decoder 15. After decoding the informed channel number, the decoded 15 stores the data to a register 16 to inform the channel number to a memory switching circuit 18. The switching circuit 18 uses the received channel number to send a signal to bus transceivers 20-23 via a bus exclusive signal line 19. The transceivers 20-23 receiving the signal allow a CPU to access a specific memory (any of 24-27).

Filed: 1983-11-22
Abstract: PURPOSE:To enable smooth moving of a recording medium by arranging a roller to make it opposite to a one-dimensional scanning light source and by pressing the medium to the one-dimensional scanning light source side by the roller. CONSTITUTION:An optical fiber tube is used as a one-dimensional scanning light source 1 and a silver salt film is used as a recording medium 3. The film 3 is pressed against the light emitting face of the optical fiber tube 1 by a roller 9 and makes a movement according to the rotation of the roller 9. Where friction coefficience between a support 1e provided to the light emitting face of the tube 1 and an emulsion face of the film 3 is small enough as compared with the friction coefficience between the film 3 base and roller 9, thereby allowing the film 3 to move by a stable speed in correspondence to the rotation of the roller 9. Then, pressure for pressing the film 3 against the light emitting face of tube 1 by the roller 9 can be very small, thereby giving few flaws to the emulsion face of the film 3 caused by the sliding contact of the film 3 with the support 1e.

Title: Transmission monitor controller
Inventor: YOSHIHARA SEIICHI
IPC: H04B17/18
Filed: 1984-10-19
Abstract: PURPOSE:To discriminate whether the transmission state is good or not to turn off the power source of a modulator if the abnormal operation of a power amplifying part is detected, by monitoring a channel gate control signal and a data output gate control signal and operating correlations to the transmission output detection signal of the power amplifying part. CONSTITUTION:In case of the normal transmission state, the output of a NOR circuit 11 is '0' because either of control signals from a control part 3 is always '1', and a switching transistor TR 13 is turned on to supply power to a modulator 4 from a terminal E because the output of an AND circuit 12 is '0' independently of the transmission output detection signal. If the abnormal state occurs, that is, control signals from the control part 3 are '0' (non-modulated) together and the transmission output detection signal is '1', the output of the NOR circuit 11 is '1', and the output of the AND circuit 12 is '1', and the switching TR 13 is turned off. Thus, the power source of the modulator 4 is turned off to cut off the transmission output.
